Same project as before but now I have diffrent Errors. fatal error C1075 and error C2450.

See in line 36, there is a brace, remove it, its not required.

Line 65, its double inverted comma, see its not in green color.

Also all the variables Mercury, venus etc are int, but you are multiplying an double to get its value, so it gives you warning converting to int from double.
